WILLIAM J. LOURY, OF PITTSBURGH, PENNSYLVANIA- CARBURETER-SUPPORT.

Application filed November 4, 1915.

To all whom it may concern:

Be it known that I, WILLIAM J. Lounr, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Carbureter-Supports, of which the following is a specification.

The object of this invention is to provide improved means for supporting the carbu reter of an automobile or boat engine, where'- by the carbureter is unaffected by the constantly changing position of the vehicle due to grades, slope and roughness of roadway, ruts, etc. As is well known, a carbureter involves more or less delicate adjustments, in connection with all of which a certain position of the carburetor is presupposed for maximum efliciency. For instance, the float which controls the gasolene inlet concededly should be maintained inhorizontal position if efficiency detracting influences are to be avoided. Normal operation cannot be had when the carbureter is tilted or inclined. Abnormal positions thereof result in irregular working, being frequently the cause of flooding the engine cylinders with gasolene, increasing the consumption to a wasteful amount, and washing the lubricant from the cylinders, pistons and packing and causing the parts to wear unduly and decreasing the power, also promoting the accumulation of carbon. Or, with the carburetor out of correct position, the gasolene may feed too slowly. Again, with the vehicle standing on a sloping roadway the resulting inclination of the carburetor permits the gasolene to escape and be entirely wasted. A

Distorting positions are particularly present in automobile engines. If climbing or descendin a steep hill, the whole mechanism, including the carbureter, is necessarily maintained at a corresponding inclination and is at once reflected in the uneven action of the carbureter. And of course the same is true of side slopes in the roadway as well as rough or rutty roadways, each and every deflection of the vehicle from its normal level position disturbing the equilibrium of the carbureter.

Appreciating the difficulties referred to and with a View to securing more uniform action from carburetors of road and water vehicles, I have provided a flexible suspending means for the carbureter whereby its entire weight is supported from above. In

Specification of Letters Patent.

Patented July 24, 1917.

Serial No. 59,545.

the present adaptation the flexible suspending means is embodied in a universal joint which aifords the support lateral movement in any direction without disturbing the carbureter. l'Vith the latter balanced on its flexible supporting means in such manner as to maintain it in its most eflicient normal position, it will retain such position, the flexat 3. i designates the inlet end of a vehicle engine manifold, and interposed between the latter and ca-rbureter outlet 3 is the flexible suspending means'which in the embodiment of Fig. 1 is in the formof a spherical ball joint 5 from which the carbureter in its entirety is suspended and by means of which it is supported. The outer shell of the joint is formed in two parts threaded together at -5, by means of which the joint may be tightened or loosened as desired. The en gine inlet throttle 6 may be arranged in manifold 4:, as here shown, or in any preferred Way.

The employment of a flexible suspendin means presupposes such arrangement an adjustment of the carburetor thatall parts are in their most efficient position when the carburetor as a whole hangs freely, suspended. In the form of carbureter here shown, it is presumed that a correct balance is had when the carburetor is suspended at its outlet 3, in such position the float chamber 7 and float 8 being horizontal. And similarly, the normal position of each and all of the other moving parts is maintained. If the carbureter is not sufliciently heavy to hold it substantially fixed in its suspended position, it may be counterweighted at its lower end as indicated at 9, the counterweight being simply secured to the bottom of the carburetor in such position as to maintain the stability of the suspended carbureter in vertical or upright position. The weighting of the carburetor on one side or the other as may be necessary to reach and maintain the normal position is of course an obvious expedient if the carbureter in and of 'itself does not afford the desired balance.

Instead of the spherical joint 5, Fi 1, the manifold 4: may be connected to t e carbureter by the vertical link. 10 and the oppositely disposed cross pins 11 and 12 here shown located, respectively, in the manifold and in the carbureter outlet-and to which the opposite ends of link 10 are connected, as in Fig. 2. This form of joint affords movement in every direction so that the stability of the c arbureter is assured re-' gardless of varying changes in the position or level of the vehicle as a Whole. Also,

in the modification aninclosing casing 18 of canvas or rubber is provided for maintaining the joint air and gas tight. The gasolene may be fed to the carbureter through a flexible hose 14, and similarly any other necessary connections are flexible, so that the position of the carbureter is not disturbed by relative movement of the vehicle.

It will be understood that the invention may be embodied in or applied to various types of carbureters, and may be advantageously utilized Wherever the engine is so movably mounted or carried as to transmit distorting movements tothe carbureter.

I claim:

l. The combination ofa carburetor support, a carbureter unit suspended therefrom and wholly sustained thereby, said unit including the air inlet, and a universal joint included in the carburetor unit suspending means whereb the carburetor will remain in normal position regardless of changes in tween the manifold and the carbureter unit for a ifording the manifold lateral movement in any direction Without disturbing the carbureter in its normal suspended ,position.

3. The combination of a carburetor support, a carburetor unit including the air inlet, a universal joint interposed between the support and carbureter unit with the latter suspended from the joint and Wholly supported thereby, whereby the carbureteris maintained in normal position regardless of changes in the position of the support, and a counterweight for the carbureter.

4. The combination with the intake of a. vehicle engine, of a carbureter unit including the air inlet, and a universal joint interposed between the intake and carbureter unit and comprising a support for the latter.

In testimony whereof I afiix my signature in presence of tWo Witnesses.
